Panasonic Canister Vacuum with OptiFlow Technology MC-CG985

The Panasonic Canister Vacuum with OptiFlow Technology MC-CG985 performed well on cleaning dirt from carpeting and bare floors and at picking up pet hair. It's quiet even while the brush roll was running on maximum suction and has a dirt sensor to alert you if an area needs another swipe or two. And, while it cleaned well, it's pricey and heavier than other canisters tested. panasonic.com.
